innwstr(3ncurses)


NAME

   inwstr,  innwstr,  winwstr,  winnwstr,  mvinwstr, mvinnwstr, mvwinwstr,
   mvwinnwstr - get a string of wchar_t characters from a curses window

SYNOPSIS

   #include <curses.h>

   int inwstr(wchar_t *str);
   int innwstr(wchar_t *str, int n);
   int winwstr(WINDOW *win, wchar_t *str);
   int winnwstr(WINDOW *win, wchar_t *str, int n);
   int mvinwstr(int y, int x, wchar_t *str);
   int mvinnwstr(int y, int x, wchar_t *str, int n);
   int mvwinwstr(WINDOW *win, int y, int x, wchar_t *str);
   int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *str, int n);

DESCRIPTION

   These routines return a string of wchar_t characters in wstr, extracted
   starting   at   the  current  cursor  position  in  the  named  window.
   Attributes are stripped from the characters.  The four functions with n
   as  the  last  argument return a leading substring at most n bytes long
   (exclusive of the trailing NUL).  Transfer stops  at  the  end  of  the
   current  line,  or  when  n  bytes  have  been  stored  at the location
   referenced by wstr.

   If the size n is not large enough to store  a  complete  character,  an
   error is generated.

NOTES

   Note that all routines except winnwstr may be macros.

RETURN VALUE

   All  routines  return ERR upon failure. Upon successful completion, the
   *inwstr routines return OK, and the *innwstr routines return the number
   of characters read into the string.

   Functions  with  a  "mv"  prefix  first perform a cursor movement using
   wmove, and return an error if the position is outside the window, or if
   the window pointer is null.
